In UK yestarday a story popped out that the goverment is trying to slowly put a stop on cryptocurrency with the help of banks which we all know is impossible to do so. Other countries have tried to ban crypto and ended up just boosting its potential and raised its profile. The banks are already using cryptocurrency to transfer high value in between other banks. Most of it is digital. Just think of how much of your money is cash and how much is on your bank card :)
